Acoustic and Seismoacoustic Profile Recorders with Hammers of “Sparker” and “Bumer” Types
Testing of the seismic streamer and digital modules for leakage, voltage and current.The Seismoacoustic source of "Bumer" type is designed for works with application of high power and has an additional benefit — change of frequency of a signal due to change of energy of a source of CSP-D. It allows to achieve increase of width of an impulse of a signal not available earlier. The increase of width of an impulse provides more big penetration with quality preservation of a single impulse.
The sparker source Sparker Squid 2000 is designed for high-allowing analog researches with a low electric power and high penetration of a signal. The source is mounted on twin-hulled ship, which is steady against towage; it is also perhaps easy to regulate deepening of a source for the best form of an impulse.

Controller depth towed streamer
Ensuring the maintenance of streamers at a given constant depth can improve the image quality of the geological environment and the safety of seismic data in a marine environment. However, implementation of this operation is very challenging due to the influence of ocean currents. This system is characterized by the following advantages:
Higher precision and flexibility in the positioning through the use of acoustic and exchange of sensors.
Reducing risks for safety and environmental protection at the expense of additional functions for lifting cables or manipulating the cables in order to prevent collisions with obstacles or weave cables.
Low maintenance costs.
Source array Bolt Airguns
Bolt Airguns seismic source has several key advantages over traditional air guns:
Air gun subarray can be extracted and lowered without the system pressure.
Reliability and repeatability of the signal:
Typically, the air gun subarray use multiple ports, resulting in venting becomes uneven. In the group with a small amount of the air gun subarray unevenly distributed air bubbles can interfere with each other, resulting in an unsynchronized signal will not repeat the form. Air gun subarray Seamap Sleeve Gun use one port at 360 degrees, which forms a spherical bubble regular shape and provides reliable repeatable signal to other air gun subarray in a group.
Sources of elastic waves:
- Sparker (1 - 2.5 kJ);
- Bolt Airguns 2800 XXL (V = 2h45 inch.cub)
- Puls- 6A / 7C (V = L 2h0,2)
Positioning system terminal buoy seismic streamer and air gun subarray SEAMAP BoyLink
GPS Tracking System monitors the position of the streamer tail buoy and the air gun subarray. The system provides up to 32 data channels and interfaces directly with the side of the vessel in a central navigation system.
High-strength casing: shock-resistant electronic module mounted in stainless, steel, ensures reliable operation of the air gun subarray on floats and the tail buoy;
Software Support Qinsy;
Two functions of data transmission: each module is equipped as a standard output RS-485 data and data transmission via a radio antenna;
19 "rack-mount controller.
Seismic station Geometrics CNT-2
Seismic is a basic unit for connection and control of seismic oblique GeoEel, and operates from a power supply of 60 V.
It provides power supply and connection to the digital modules.
It accepts a trigger signal from the controller of the seismic signal source (usually air gun subarray controller).
Optionally can send a trigger signal to actuate the air gun subarray.
It provides an interface between system management controllers depth and depth controllers themselves.
The ability to use up to 8 channels of service.
